There is actually some incorrect info on that page

This is just one instance. Quoted from link......

The next trouble-shooting task begins by disconnecting the wire to the tank sending unit. If the gauge still reads full, there is likely a short to ground somewhere between the sending unit and the gauge

It should say it is likely open between the gauge and sending unit. It is supposed to read full with the wire disconnected.

Look here. hope this helps.
